Offline Deployment

In some corporate environments, embed.diagrams.net is blocked by network policies. This guide explains how to deploy Next AI Draw.io in offline/air-gapped environments using a self-hosted draw.io instance.

Overview

By default, Next AI Draw.io uses embed.diagrams.net for the diagram editor. For offline deployment, you need to:

1. Run a local draw.io instance
2. Build Next AI Draw.io with a custom NEXT_PUBLIC_DRAWIO_BASE_URL

Important: This is a build-time configuration. You need to rebuild the Docker image to change the draw.io URL.

Quick Start

Create a docker-compose.yml:

services:
  drawio:
    image: jgraph/drawio:latest
    ports:
      - "8080:8080"

  next-ai-draw-io:
    build:
      context: .
      args:
        - NEXT_PUBLIC_DRAWIO_BASE_URL=http://drawio:8080
    ports:
      - "3000:3000"
    env_file:
      - .env
    depends_on:
      - drawio

Then run:

docker compose up -d

Local Development

1. Start a local draw.io instance:

docker run -d -p 8080:8080 jgraph/drawio:latest

2. Add to your .env.local:

NEXT_PUBLIC_DRAWIO_BASE_URL=http://localhost:8080

3. Rebuild and run:

npm run build
npm run start
